Upgrading to Redhat 5.7 Os with NBU 6.5.4 question

Hi All,

I have a question. I have my legacy backup system running NBU 6.5.4. We are planning to upgrade the LINUX OS for the media server which is currently running version Red Hat Enterprise Linux Server release 5.3   x86_64 GNU/Linux. IS NETBACKUP 6.5.4 compatible with Red Hat OS 5.7????
